Plastic building blocks are good for building molecules because of some useful properties which they possess. For instance, plastic are flexible, they can be easily manipulated and can be made into any shape, size and combination. They can also be produced using different colors. Because of these features, they can be used to build and to explain how molecules behave.

Consider the following equilibrium:
irga5000 [103]

Consider the following equilibrium:

4NH₃ (g) + 3O₂ (g) ⇄ 2N₂ (g) + 6H₂O (g) + 1531 kJ

The given statement is True, because

According to Le Ch's Principle:

Systems that have attained the state of chemical equilibrium will tend to maintain their equilibrium state.

External factors such as the addition of products and reactants result in the disruption of the equilibrium state.

we expect the system to shift to the direction that offsets the change in concentration.

This results in the state of chemical equilibrium to be reestablished.

Hence, The statement is true,

  • The addition of more ammonia (a reactant) would offset the state of equilibrium.
  • To restore chemical equilibrium, the system must consume the excess reactants to form more products.
  • A shift to favor the products side occurs.

For the reaction: N2(g) + H2(g) → NH3(g)
gayaneshka [121]

The rate of increase of NH3 is 0.22M/s.

<h3>What is the balanced equation of the reaction?</h3>

The balanced equation of the reaction is given below:

  • N2(g) + 3 H2(g) → 2 NH3(g)

The rate of decrease of N2 is half the rate of increase of NH3.

Rate of decrease of N2 = -0.11 M/s

Rate of increase of NH3 = 2 × +0.11 M/s = 0.22M/s.

In conclusion, the rate of formation of products is dependent on the rate of disappearance of reactants.
